Adam Stainless is a trusted stainless steel 305 nut manufacturer and supplier in Canberra, Australia, providing precision-engineered fastening solutions to perform to demanding industrial requirements. Our 305 nuts are built for high corrosion resistance and better cold-forming properties. They are renowned for being non-hardenable and thus offer high ductility and mechanical properties. Made with best-in-class raw materials and state-of-the-art technology, these nuts provide long-term reliability and durability. Adam Stainless follows rigorous quality control procedures in accordance with international specifications. Our Stainless Steel 305 Nuts are widely applied in loading situations where secure fastening, along with greater workability and oxidation resistance, is needed.
Stainless Steel 305 Nuts consist of roughly 17–19% chromium, 10–13% nickel, and trace amounts of carbon. The high nickel content of this alloy enhances its deep drawing and cold-forming strength with great corrosion resistance. Mechanical properties encompass a tensile strength of approximately 515 MPa, 205 MPa yield strength, and elongation of approximately 40%. Good toughness and ductility of the material are maintained even at sub-zero temperatures. The 305 grade nuts show superior resistance to oxidation, atmospheric corrosion, and a number of organic and inorganic chemicals and hence are used in precision work.
